Construction of Natural Gas Pipeline (Shizuoka Line) now Complete

INPEX Holdings Inc. is pleased to announce that Teikoku Oil Co., Ltd., (Head office: -ku, , President: Masatoshi Sugioka), a wholly-owned subsidiary of INPEX Holdings, has completed construction of the Shizuoka Line commenced in 2003.

This Shizuoka Line is a pipeline constructed to receive vaporized LNG from the “Shimizu LNG Sodeshi Base” via Shizuoka Gas Company. Constructed simultaneously with the “Minami Fuji Trunk Pipeline” (constructed in collaboration with Shizuoka gas Company and Tokyo Gas Co., Ltd., and scheduled for completion this month), this line will connect with the Minami Fuji Pipeline to enable the supply of vaporized LNG.

By ensuring two sources of gas - domestically produced natural gas from the Sea of and vaporized LNG from the Pacific Ocean - this line will greatly improve stability of supply and will enable a continued stable supply even in the face of growing demand in the future. As applications of natural gas continue to increase, INPEX Holdings aims to further promote natural gas utilization with the help of urban gas suppliers and customers in commerce and industry.
